In wireless applications, phase-locked-loop frequency synthesizers require very good phase noise performance in order to obtain a good signal-t-noise ratio for the desired signals even in the presence of very large nearby unwanted signals. Inside frequency synthesizers, thermal noise generated by th.....

Fluorescent lamp is a common form of illumination in offices, public areas and even households. However, it is much harder to provide dimmable control for fluorescent lamps when compared with incandescent ones. A new method is now invented in achieving control over dimming function for fluorescent.....

This is a method which is efficient in improving the percolation efficiency of the electrically conductive adhesives (ECAs). We apply a series of halogens and pseudohalogens for surface pre-modification of the conductive fillers. This treatment can result in the formation of a thin layer of nano-isl.....
